Influence of diet on occult blood tests.
نویسنده
چکیده
There is a dearth of experiment on the human subject. Test-tube experiments on foodstuffs are helpful, but are not sufficient to allow of dogmatic statements about their dietary influences. To advise an unrestricted diet and give significance only to strongly positive reactions is an approach with a superficial appeal (Ratnoff, 1923; Alvarez and Wight, 192); Levin and Watt, 1949; Needham and Simpson, 1952; Mason and Belfus, 1952; Barnett, 1952; Todd, Sanford, and Wells, 1953; Forshaw and Mason, 1954; Smith, 1958; Jones and Gummer, 1960; Cameron, 1960), but such an approach will lead, as is apparent in the work of these authors, to an appreciable number of falsepositive results due to meat in the diet. All other contributors to the literature specify that the diet shall be meat-free but do not define what they mean. Although Dewis (1907), Leech (1907), Mackay (1916) and Gregersen (1917) state that eating fish will not cause false-positive results, there is contrary opinion (Joslin, 1906; White, 1907; Aaron, 1924; Leiboff, 1929; Kiefer, 1934; Gettler and Kaye, 1943; Kolmer, 1943; White and Geschickter, 1948; Kolmer, Spaulding, and Robinson, 1952). Poultry is forbidden by Mackay (1916), by Lipetz (1947), and by Warner (1950) but permitted by Leech (1907) and Bramkamp (1929). Green vegetables have also provoked contention. Barrett (1936) claims that their inclusion in the diet will tend to produce false-negative results. Other workers believe that green vegetables are permissible (Adler, 1921; Johnson and Oliver, 1941; Kohn and O'Kelly, 1955); but whereas Alvarez and Summerskill (1958) and Winkelman and Summerskill (1961) exclude only spinach from the vegetables in the diet of the patient under test, there are many who prohibit all green vegetables (Stone, 1907; Clark, 1909; Mackay, 1916; Reimann, 1923;
